We have a customer that would like to run an E40 with a 6L80 T43 in an off roader.

He would like the tap up/down functions to work.

Does any body know if it is possible to run this combination. All of our wiring diagrams, for Holden, show that you need a BCM with CAN bus communication.

Or is there aftermarket units that could can run a 6L80?

Cheers for your time.
